MDD090A-N-020-N2L-130PB2

The Bosch Rexroth Indramat MDD090A-N-020-N2L-130PB2 is a high-performance member of the MDD Synchronous Motors line designed for precision motion control in demanding industrial environments. As a Digital AC Servo Motor, it delivers reliable position and speed regulation via integrated permanent-magnet technology. Featuring a robust Motor Size of 090 and compact Motor Length Code A, this unit optimizes power density while maintaining structural integrity. The motor’s design includes a Centering Diameter of 130 mm and a keyed shaft per DIN 6885, providing precise coupling and torque transmission. With an optional blocking brake delivering 11.0 Nm Holding Brake Torque, it ensures secure stops in vertical and safety-critical applications.

Engineering specifications of the MDD090A-N-020-N2L-130PB2 are grounded in proven digital drive architecture. It employs Digital Servo Feedback (DSF) for high-resolution commutation and encoder feedback, enabling closed-loop control of rotor position and speed. The motor offers a Nominal Speed of 2000 min⁻¹ and a Continuous Torque at Standstill of 3.7 Nm, making it suitable for both dynamic positioning and holding functions. The Standard Balancing configuration minimizes vibration at high speeds, while the Standard Housing ensures mechanical protection and thermal stability. Built-in Shaft Seal and a Keyway Shaft Type conform to industrial sealing and mounting standards.

Operational performance of the MDD series motor emphasizes responsiveness and durability. The integrated permanent-magnet rotor and efficient thermal management support repeated duty cycles without compromise. With Connection Type: Connector on Connection Direction: Side B, installation and maintenance time are reduced, and clear electrical interfacing is assured. The design includes a Standard (without side B shaft end) Shaft End, eliminating the need for custom machining. The combination of compact form factor and precise motor feedback yields rapid acceleration, minimal overshoot, and consistent torque across varying loads. The robust braking system activates within milliseconds, holding loads securely under power loss or commanded stop conditions.

System integration is streamlined by compatibility with Bosch Rexroth Indramat digital drive controllers and standard servo amplifiers. As a dedicated Motor for digital drive controllers, the MDD090A-N-020-N2L-130PB2 supports advanced control algorithms, including auto-tuning and vibration suppression. Its compact dimensions and standardized interface simplify retrofits and new machine designs in sectors such as packaging, robotics, and CNC machining. The motor’s precise feedback and braking capabilities make it ideal for applications requiring high repeatability, safety interlocks, and tight process control.
